Either the bravest SOB in World of Warcraft history, or the stupidest; depending on your point of view. Rushed into an enemy stronghold alone, roaring his name; forcing the rest of his guild to follow and turning their chances of victory from 32.33(repeating)% to zero. At least he has chicken.

To "pull a Leeroy Jenkins" is to rush into a dangerous situation alone without following strategy, forcing your allies to follow and leading to the inevitable, definitive, graphic demise of your team. In essence, your entire team got wombo comboed because of you. If you don't try to laugh this off by saying, "At least I have chicken", or at the very least acknowledge your foolishness, you not only fail at the game, you fail at life.
Note: NEVER try to pull a Leeroy Jenkins if you're an actual member of the military. Chances are no one will make it out alive. And you won't even have chicken to comfort you.
"All right chums, let's do this. LEEROOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOY Jeeeeeenkins!"
"You really pulled a leeroy jenkins on that one, dumbass."

Leeroy Jenkins- Doing it Leeroy Jenkins Style. Meaning to do something so bloody wild that youll be talked about for months because it was bloody insane.
Running into a Boss in a dungeon in World of Warcraft Solo Taking on mobs of up to 100 all level 55 screaming "LEEEEERRROOOOYYY JJJJENNNKKINNSSSS!!!"

The above is a classic example of "Doin it Leeroy Jenkins Style"

When you and your partner discuss at long the intentions of your sexual persuits right before you make love. Then at the last second the male abandons all this and screams, "Leeroy Jenkins!" and just penetrates and goes to town.
We spent an hour cuddling and "planning" last night before me and my wife were going to do it. Then right when she was ready to start pulled The Leeroy Jenkins, screwed the plan and went right in!
